That’s great! (IMO) when your bird figures out it is not just making a noise or repeating a noise but figures out functional vocalizations, you are on your way to a bigger and easier relationship. Enunciating the word and emphasizing the sounds she’s missing may help the word to get clearer.
My last Quaker had many functional vocalizations. Other good ones are: “want some, want drink, thank you, goodbye, out, stop it, whisper/ quiet, cage, good night or go night night.”
For clear talking: With my Quaker, I would emphasize the sounds that she was missing or saying too softly. So, for example, Lucy came with the phrase “stop it!” but it sounded like “fop Id”. Somehow it became necessary to fix that pronunciation so I would repeat “SToPP iTT.” Because, unfortunately, she would yell at herself and me a lot in the beginning. Or, she said “wisp-bird” and I would repeat “wisPEr”.
Except for when the mistakes were too cute and then she could keep them.
Your heart will warm when Ona calls you a “good good bird” or a “pretty bird” for the first time. I think that Ona will just naturally pick up some words, too.
Ona seems like a wonderful little bird. If she needs a godmother, I am here (for emergency bird home).
